Abstract (en)
[origin: WO2014037374A1] A composition [composition (C)] comprising at least one poly(aryl ether ketone) polymer having a melt flow rate (MFR) equal to or higher than 8 g/10 min at 400°C and under a load of 2.16 kg, [(PAEKHMF) polymer], from 0.1 to 50 wt. % of at least one poly(tetrafluoroethylene) polymer having a D50 particle size equal to or below 10 mum, and having a melt viscosity equal to or lower than 1x105 Pa.s at 372°C, from 0 to 50 % wt. % of at least one poly(aryl ether sulfone) polymer having a melt flow of at least 15 g/10 min at 365°C and under a load of 5.0 kg, [(PAES) polymer], from 0 to 50 % wt. % of at least one reinforcing filler, with the proviso that - should the composition (C) comprise a (PAES) polymer having MFR of more than 22 g/10 min, then the (PTFE) polymer is present in an amount of less than 40 wt. %, and - should the composition (C) comprise a (PAES) polymer having MFR of 22 g/10 min or less, then the (PTFE) polymer is present in an amount of less than 30 wt. %, and wherein all % are based on the total weight of the composition (C).
